Brain-wave / EEG coupling

Emerging research

An early, active research area. Microbial signals reach the brain via the vagus nerve and short-chain fatty acids, and studies are beginning to link the microbiome to sleep-stage and EEG patterns. Genuinely promising — but not yet settled science.

This one acts on the whole community rather than a single taxon — see the description above.
